APPARATUS FOR EXTRACTING O IL OR GFiEASE.

SPECIFICATION forming part of Letters Patent No. 685,529, dated October 2 9 Original application filed March 14, 1901, Serial To on whom it may concern:

Beit known that I, EMANUEL PRINTZ, acitizen of the United States, residing in the-city and county of Philadelphia, State of Pennsyl- 5 Vania, have invented a new and useful Improvement in Apparatus for Extracting Oil or Grease from Leather, Wool, Yarn, &c., of which the following is a specification.

My invention relates to an improvement in apparatus for extracting oil and grease from leather, wool, yarn, &c.; and it consists in employing racks suitably journaled and upon which the material is suspended and in means for imparting a rocking motion to the racks.

It further consists of novel details of construction, all as will be hereinafter set forth, this application being a'division of an application for patent for a process of and ap paratus for extracting oil and grease from leather, wool, &e., filed March 14, 1901, Serial No. 51,049, and I do not therefore claim in this application the process described and claimed therein.

Figure 1 represents a perspective view of a chamber or compartment employed, showingaportion of the walls thereof broken away and certain mechanism connected with said chamber. Fig. 2 represents avertical section thereof. Fig. 3 represents a perspective view showing the manner of suspending the material on the racks. Fig. 4 represents a vertical sectional view of an apparatus, showing a different form.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a tank or compartment having suitable openings in the walls thereof and doors B therefor, with suitable means for locking said doors.

designates shafts suitably journaled in the walls of the compartmentA, having, preferably, one end thereof extending beyond the same and being further supported or journaled in the uprights or standards D, the ends of said shafts being suitably connected with y the levers E, which are movably connected with a rod or bar F, to which power is applied in any suitable manner to impart an up-and- 50 down movement thereto, whereby the levers No. 51,049. Divided and this application filed April 30, 1901. Serial (No model.)

'E are moved and operate to turn the shafts O. Mounted on the shafts O are the arms G and H, on which are adapted to rest the rods or bars J, suitable means, such as set-screws K, being employed to lock the rods J when in position.

In Fig. 2 I have shown the material L-such as hide, leather, &e.in position on the rods J, the same being held by means of a wire M or other suitable fastening devices passing 6o therethrough and over the rods J, as is also seen in Fig. 3. Any suitable cleansing or scouring material N is placed in the receptacle, and, if desired, heat may be imparted to thechamber or any other suitable means em- I have also shown aeoil of pipes R in the lower portion of the tank in lieu of the cham-v ber P, the effect being the same.

The operation is evident. The material to be scoured or degreased is placed upon the rods J, after which motion is imparted to the shafts C, whereby it will be seen that an upand-do'wn ora vertical movement is imparted to the material, whereby and at the same time a movement from side to side results, so that the material is subjected to agitation, the of feet of which is evident.

It will be evident that slight changes may be made by those skilled in the art which will come within the scope of my invention, and I do not therefore desire to be limited in every instance to the exact construction I have herein shown and described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isg 1. In an apparatus for extracting oil and grease from materials, a closed compartment,

- a plurality of independently-mounted means for suspending the material therein, and means for imparting a simultaneous up-and- I00 down and side movement to said means and material.

2. In an apparatus for extracting oil and grease from materials, a closed compartment, shafts suitably journaled therein, means for imparting movement to said shafts, arms carried by said shafts, and means disposed at an angle to said arms for openlysuspending, the material upon said arms.

3. In an apparatus for extracting oil and grease from materials, a closed compartment, shafts suitably supported therein and projecting beyond the Walls thereof, arms carried by said shafts, means over which the material may be hung for supporting the material upon said arms, a lever connected with said shafts, and a rod for imparting movement to said levers.

4. An apparatus for extracting oil and grease from materials, a closed tank, means for heating the same, shafts journaled therein, open arms on said shafts for openly suspending the materials and means for imparting a rocking motion. to said arms.

5. An apparatus for extracting oil and grease from materials, a closed tank, shafts journaled therein, arms on said shafts for supporting the materials in an open suspended condition and means for imparting a complete revolution to said arms around said shafts.

6. In an apparatus for extracting oil and grease from materials, a tank, shafts journaled therein, a plurality of separated arms supported on said shafts and rods supported between each pair of arms and disposed at substantially a right angle thereto for supporting the material in an open suspended condition.
